WINDOW CONSTRUCTION.

SPEOIFICATION f0rming part of Letters Patent No. 790,215, dated May 16,1905.

Application filed March 1'7, 1904. Serial No. 198,682.

To aZZ whom, it may concern:

Be it known that I, EDMUND I-I. LUNKEN, a citizen of the United States,residing at Oincinnati, Ohio, have invented certain new and usefulImprovements in Window Constructions, of which the following is aspecification.

My invention relates to window constructions, and more particularly tothat form of window construction disclosed in an application for LettersPatent of the United States, No. 173,118, filed by myself and Bernard J.Hausfeld, as joint inventors, September 14, 1903, in which application ametallic window structure is disclosed in which a main frame carriespivotally a swinging frame, which latter in turn carries the sashes.While I have shown my invention as adapted more particularly for awindow construction of the form shown in the said application, I wish itunderstood that I do not limit myself in this respect, as certainfeatures of my invention are applicable to other forms of windowconstructions than that referred to.

My invention consists in the features and combination and arrangement ofparts hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view showing oneembodiment of my invention. Fig. 2 is an enlarged horizontal sectionaliew taken at the point above where the inner swinging frame (not shown)is pivotedto the main stationary frame, the said figure showing only oneside of a window with the improved frame walled in position. Fig. 3 is ahorizontal sectional view similar to Fig. 2, showing the main woodenframe before the metallic sections are applied thereto and withprotectingstrips secured to the wooden frame to shield the same whilethe building is in the process of construction. Fig. 4 is a detailperspective view of the angle-iron section of the frame. Fig. 5 is adetail view in perspective of the main member of the frame. I Fig. 6 isa detail sectional view of a modified form of the invention.

One of the objects of my invention is t provide a main frame which willallow adone of which is shown at 1, Figs. 2 and 3, ar-

ranged in the wall of the building and forming the top, bottom, andsides of the frame, the said pieces projecting from the wall into thewindow-opening. On these projecting portions or edges the other memberof the main frame is supported adjustably. This adjustable member in thepresent embodi- .ment of my invention consists of metallic frame members2 and 3, angular in crosssection. These are each of substantiallyright-angular form and have their side flanges 2 and 3 arranged againstthe opposite side faces of the wooden frame, while .their other flanges,2 and 3, extend across the inner face of the wooden frame member 1, thesaid flanges 2 and 3" being in the same plane and having their edgessubstantially abutting each other. The angular frame-sections areclamped to the frame 1 by bolts 4, extending through the side flanges ofthe angle-iron frames and through openings or recesses 5, formed in theinner edge of the wooden frame members 1, or, if desired, throughopenings formed through the members near their inner edges. The recessesor openings, as the case may be, are somewhat larger than the bolts, sothat in case it is desired to change the position of the metallic frameor member in relation to the wooden members 1 it will simply. benecessary to loosen the bolts 4, adjust the metallic framesections intoproper position, and then tighten the nuts of the bolts, thus securing.the metallic portion of the main frame in the desired relation to thewindow-opening, and in this adjustment it will be understood that theinner swinging or sash-carrying frame will be adjusted also, for thesaid inner frame is supported on the adjustable metallic mainframesections, for which purpose the sockets IOO .member 1.

6 for the pivots of the swinging frame are supported on the angle-ironframe-section 3.

As fully described in the above-mentioned application, stop-strips areemployed on the main frame and also on the swinging frame designed toclose the space between these frames, and in the present case thesestopstrips also are carried, as shown at 7, by the angle-ironframe-section 3.

In order to present a finished appearance, I provide finishing-strips 9of sheet metal, arranged to fit in the corner between the wall and theframe member 1, one flange of the said sheet-metal strip being heldbetween the flange of the angle-iron frame-section and the side of themember 1, while the other flange, 1.1, of the finishing-strip fits in arecess in the mortar 10 and against the side of the wooden Thesefinishing-strips may be of any desired ornamental appearance or they canbe entirely dispensed with and the 6X posed woodbetween the wall andangles can be covered with athin sheet of metal, extending from underthe angles to cut-out portions in the mortar.

The size of the openings or recesses in the wooden frame 1 in relationto the diameter of the bolts will permit adjustment of the metallicframe members either vertical or horizontal, and it will be noticed thatthere is sufficient space left between the flanges 2 and 3 and the innerface of the frame member 1 to allow this adjustment to be made, and inall positions of the metallic members in relation to the window-openingthe finishing-strips will serve to entirely hide the wooden framemembers, and the inner projecting portion of these members will beentirely covered by the metal. The metal frame member is made in twoparts to facilitate the removal or the placing of the same, the saidmetal frame being removable as well as adjustable.

While the building is in process of construction, the wooden framemember 1 may be protected against damage by strips 11, secured to theside and inner faces of the said wooden frame or member, and thesewooden strips will notonly serve as a shield, but also they will act asa guide for the bricklayers in walling up the frame to theprotecting-strips.

I do not wish to limit myself to the use of a wooden frame member 1, assuch member may be of metal in the form of a shell or be a solid-metalframe.

Referring to Fig. 6, the member 1 of the main frame, which is walled inthe buildin is composed of aflat piece, preferably of metal, projectinginto the window-opening. The angle frame-sections 2 and 3 areadjustablysecured thereto by the bolts 4 passing through the flanges ofthe said angle framesections and through enlarged openings in the member1 The socket 6* for the swinging frame and the stop-strip 7 X are car:

ried by the angle-section 3 It will be noticed that this form of theinvention, like that first described, includes a walled-in membercarrying adjustably another member composed of two angle-sections; butinv the present case the free flanges of the anglesections instead ofbeing directed toward each other are directed away from each other. Inthis form, however, the projecting part of the walled-in member isembraced by the sections of the other member. Packing 12 is interposedbetween the angle-iron sections and the member 1 to obtain a tightjoint. The belt 4 has a square portion under its head which fits in asquare opening in the flange of the angle-iron section. Finishingstrips13 are sprung into place between the flanges of the angle-iron sectionsand the wall, being held in place simply by the s )ring tendencies ofthe flanges 14- of the finishingstrips. In both of these forms shown thesupplemental frame, composed of angle-iron, is adjustable on the mainWalled-in member by simply loosening the bolts, adjusting the frame, andthen tightening the belts with the frame in the adjusted position.

Instead of holes being formed in the members 1 recesses or grooves maybe formed in the inner edge thereof.

The sockets for the pivots of the main frame and the closing-strips arearranged on the angle-irons, and both may be arranged on the sameangle-iron. This is true also of that form of the invention shown inFigs. 1 and 2 i. 0., both the pivot-socket and the stop-strips may beplaced on the same angleiron. I do not wish to limit myself to formingthe enlarged openings in the main-frame members, as it will be obviousthat the secondary frames may be provided with enlarged openings, ifdesired. Neither do I limit myself to the second main-frame membercomposed of two sections, as said member may consist of only one sectionor piece, as shown and described in an application filed by me of evendate herewith.

I claim as my invention 1. In combination in a window construction, aframe member secured to the wall of the building andprojecting into thewindowopening, and a second frame member and bolts for holding themembers together said bolts passing through openings of larger size thanthe diameter of the bolts to allow adjustment in all directions wherebythe second frame member will be supported wholly by the first framemember and adjustably clampedthereto so as to be moved vertically,laterally, or tipped in relation to the first frame member, said secondframe member being removable from the first frame member, substantiallyas described.

2. In combination in a window construction, a frame member secured tothe wall of the building and projecting into the windowopening, a secondframe member and bolts for holding the members together said boltspassing through openings of larger size than the diameter of the boltsto allow adjustment in all directions whereby the second frame memberwill be supported wholly by thefirst frame member and adjustably clampedthereto so as to be moved vertically, laterally, or tipped in relationto the first frame member, and a swinging frame carried by the saidsecond frame member, substantially as described.

3. In combination in a main frame for a window, a frame member to besecured to the wall of the building and to project into thewindow-opening, and a second frame member composed of a pair ofangle-irons with flanges resting against the outer sides of the framemember first mentioned and bolts each of which passes through the saidflanges and through enlarged openings to hold thesecond frame member,substantially as described.

4. In combination in a window construction, a main frame com rising aframe member to be secured to the%uilding and projecting into theopening, a second frame member adj ustably mounted on the first framemember to compensate for settling of the building and carrying a windowpart or parts and finishing-strips between the adjustable frame memberand the wall of the window-opening, said finishing-strips extending overthe sides of the projecting portions of the member first mentioned,substantially as described.
